Decanter Centrifuge is the final-stage fine solid separation equipment in oil & gas drilling solids control systems, used to remove 2–7 μm fine solids and recover barite, reducing mud density and maintaining drilling fluid performance.

The Function of decanter centrifuge：

The 5th and last phase of solids control (after shale shaker, desander, desilter, mud cleaner).

Separates fine solid particles (2–7 μm) from drilling fluid; recovers valuable barite; lowers mud density; reduces waste discharge.

The working principle of the decantercentrifuge:

It uses high centrifugal force (G=800–2,100 ) for continuous solid-liquid separation.Drilling mud enters the rotating drum through the feed pipe.High-speed rotation (1,500–3,500 RPM) generates strong centrifugal force. Denser solids settle to the drum wall,lighter liquid forms an inner layer.

Main components of the decanter centrifuge：

The high-speed rotating drum,Spiral Conveyor,Differential Gearbox,Motors,auxiliary motor,Frame & Casing.

The advantages of decanter centrifuges in solid control：

Fine Solids Removal: Eliminates 2–7 μm particles that damage mud properties and equipment.

Barite Recovery: Recycles valuable weighting material, reducing costs.

Density Control: Lowers mud density by removing low-specific-gravity fine solids.

Waste Reduction: Minimizes drilling waste discharge, meeting environmental regulations.Continuous Operation: processing with high efficiency.
